It's more fun than any mobile game I have playedor seen.
Controls work good on pc.
The devs made it to function well on low spec pc for the internal market. So it probably influenced the looks since mobile games use the same tricks to run on phones.
Hell, my only complaint so far is that the payed skins are ugly compared to the ones you get by grinding for them with weapon xp for free by just playing the game with a weapon you already like.
Oh and so far their are only two kill streak rewards and no mini map. So no radar or uav. Just minigun and nuke.
